Here is how Jeremy explained it
A good reason to look for mods with dual batteries or high mah packs.
The Steam Engine calculator added a page for finding the optimum coil ohm for a device. Handy.
Haha, complex question. To an extent yes but you must be ohmed up so battery and chip is capable of amp load your asking for.
The sigelei will maintain constant voltage/ wattage through most the charge with one battery (input voltage of 4.2-3.2) if you are at 2.4 ohms or above for the sigelei.
Since I want that consistency running below 2 I use the stacked setup because I have an input voltage of 8.2-6.4 so I always have more than 6v available to deliver to the coil. 2 more volts run time and a lower amp load on the batteries. Making the setup last a long long time at high wattages..
I think all mods will produce lower power as the battery drains unless you are in the median range of the device. Where with a low 3.3v input it can be converted to desired wattage or the maximum wattage... I don't think a DNA 30/40, or any other higher wattage mods running single batteries; will be able to put out their rated maximum output when the battery is below a 3.7v input.
The benefit of stacking batteries is that you have an input of 8.4v of power.
Sigelei took notice and their 100w is a stacked/series setup.
